🧪 Physical Properties

• Appearance: A colorless to pale yellow transparent liquid at room temperature.
• Melting Point: ~3 °C.
• Boiling Point: Ranges between 258 °C and 260 °C at standard pressure (760 mmHg).
• Density: ~1.375–1.4 g/cm³ at 20–25 °C (heavier than water).
• Solubility: Highly soluble in common organic solvents such as benzene, chloroform, carbon tetrachloride, and ether. It reacts vigorously with water and decomposes in hot alcohols.2

⚗️ Chemical Properties

• Chemical Formula: C₆H₅Cl₂OP (Molecular weight: ~194.98).
• CAS Number: 824-72-6.
• Reactivity & Decomposition: This compound is highly sensitive to moisture. Upon contact with water, it undergoes hydrolysis to form phenylphosphonic acid and hydrogen chloride (HCl) gas.
• Incompatibilities: It is strictly incompatible with strong oxidizing agents, alkalis, active metals, and water. Due to the presence of two highly active chlorine atoms, it readily participates in condensation reactions with amines, alcohols, and other monomers.2

🏭 Main Uses

• Chemical Intermediates: Widely utilized as a crucial intermediate in organic synthesis for producing various organophosphorus compounds and biologically active molecules containing phosphorus.
• Polymer Synthesis: Reacts with hydroquinone via dehydrochlorination condensation to generate flame-retardant phosphorus-containing polymers. It is also used as a thermal stabilizer for polyesters.
• Plasticizers & Esters: In the presence of pyridine, it reacts with octanol to produce phenylphosphonic acid octyl ester, which serves as a low-volatility plasticizer.
• Pharmaceutical & Agrochemical Production: Acts as a vital precursor in the manufacturing of specific pesticides and pharmaceutical intermediates.2
